The aim of this helper function is to URI-encode given string twice. There's a bug (fixed in next commit) in which we're unable to fetch .vmx file for a domain if corresponding datastore contains some special characters (like +). Cole Robinson discovered that encoding datastore twice enables libvirt to work around the issue [2]. Well, this function does exactly that. It was tested with the following inputs and all worked flawlessly: "datastore", "datastore2", "datastore2+", "datastore3+-@", "data store2+".

It's nit-picky but should we explain here why we are double-encoding the string (ie. to workaround a VMware bug)? But other than that, for the whole series: Reviewed-by: Richard W.M. Jones <rjones@redhat.com> Rich.
